摘要:
Disclosed herein is a nanostructured thin film. The nanostructured thin film comprises a nanoparticle layer and a number of micro-undulated surfaces formed on the nanoparticle layer. The two micro-undulated structures of the nanostructured thin film are uniformly introduced over a large area. This configuration makes it easy to control the surface properties of the nanostructured thin film. Therefore, the nanostructured thin film can be widely applied to a variety of devices. Also disclosed herein is a method for controlling the surface properties of the nanostructured thin film.
摘要:
A porous carbonaceous composite material, a positive electrode and lithium air battery including the porous carbonaceous composite material, and a method of preparing the porous carbonaceous composite material. The porous carbonaceous composite material includes a carbon nanotube (CNT); and a modified carbonaceous material doped with a heterogeneous element, wherein the ratio of the number of surface oxygen atoms to the number of surface carbon atoms ranges upward from about 2 atom %.
